Hi, who can solve this Maths trick and get the answer correctly

Re: Brain Teaser, Who Can Solve This Maths Trick by mascot87(m): 7:25pm On Apr 28
The answer is 54

Calculator = 4
Clock = 10
Bulb = 5

4 + (10 x 5) = 54

Correct

From the image:
⏰ + ⏰ + ⏰ = 30
→ Each clock = 10
⏰ + 💡 + 💡 = 20
→ 10 + 2 bulbs = 20
→ 2 bulbs = 10 → Each bulb = 5
💡 + 🧮 + 🧮 = 13
→ 5 + 2 calculators = 13
→ 2 calculators = 8 → Each calculator = 4

Final line:

🧮 + ⏰ × 💡

Apply BODMAS (multiplication first):

→ 4 + (10 × 5)
→ 4 + 50
→ 54 ✅

This one is too kindergarten for my level.
Re: Brain Teaser, Who Can Solve This Maths Trick by Diamonddris(m): 1:44pm On May 02
The answer is 70...

4+10x5=70
Re: Brain Teaser, Who Can Solve This Maths Trick by telim: 1:44pm On May 02
Let the clock be x, let the bulb be y and let the calculator be k

x + x + x =30
3x = 30
x = 30/3 =10

10 + y + y = 20
10 + 2y = 20
2y = 20 - 10
2y = 10
Y = 10/2 = 5


Y + k + k = 13
5 +2k = 13
2k = 13 - 5
2k = 8
K = 8/2 = 4

Input the above values into iv we have

K + (x × y) = 4 + (10 × 5)
4 + 50 = 54

Except the BODMAS rule isn't applicable

Re: Brain Teaser, Who Can Solve This Maths Trick by Kylekent59:
Exactly what happens when you go for an examination and came out claiming you scored everything, but you failed woefully


Hahahahahaaha


You have to watch all diagrams carefully, there are lots of differences.

Where many made a mistake was observing the diagram.


If three clocks are at 12 o' clock equal 30

What would the one at 7 o' clock and 36 seconds past be?


How about the one at 12 o' clock and 20 seconds?

Hahahahahah

You don't just assume all are the same

I pity people who refuse to learn.

Calculator:4

Clock: 10

Light bulb: 5

4 + 10 × 5 = 70.

Not enough information provided.

Calculator type, make and model not provided.

You failed everything

Have you observed the clock?

One is 12 o' clock, one is 7 o' clock and other is 12 and four seconds.....

Have you observed the bulbs? One in the middle is top shaded, while another is unshaded?

Have you observed the calculator?

We have three different types based on the diagram.



In mathematics, observe before solving.

Apply BODMAS
54 is the right answer.

illicit:
14 times 5

The answer is 70

Yes
Re: Brain Teaser, Who Can Solve This Maths Trick by Bunnatex(m): 2:20pm On May 02
Look at the images closely and you'll see ras they are slightly different. Eg the time on the clock in the second picture
Re: Brain Teaser, Who Can Solve This Maths Trick by Mankind2024: 2:22pm On May 02
use BODMAS
Multiplication must come b4 addition.


Major001:
Calculator:4

Clock: 10

Light bulb: 5

4 + 10 × 5 = 70.

Wrong. Look at what the time is in each clock.
Re: Brain Teaser, Who Can Solve This Maths Trick by AbuAeesha: 2:44pm On May 02
Answer is 54
4+(10x5) = 54
Clock _10
Bulb _5

I'm mathematics, observe before solving.
He got everything right, actually. Infact, his approach is top notch. He solved it like a real mathematician would. I guess he's a mathematics student himself, if not, perhaps engineering.

The OP himself has confirmed the rightness of his - telim - approach and answer.

According to the OP, it never mattered what time it is, in the clock, or how the calculator and bulb looks like. What matters is what the clock, calculator and bulb represents as a whole, which is 10, 4, and 5 respectively.
Re: Brain Teaser, Who Can Solve This Maths Trick by guass(m): 2:54pm On May 02
